SHOE-SOLE AND METHOD MAKING THE SAME.

Specification of Letters Patent.

Application filed January 24, 1916. Serial N o. 73,875.

To all whom it may concern:

Be it known that FERNANDO ALONSO YZAGUIRRE and JULIO YZAGUIRRE VILLA, subjects of the King of Spain, residing at Old Glamis Road, oft' Clepington Road, Dundee, Scotland, have invented new and useful` Improvements in Shoe-Soles and Methods of Making the Same, of which the following is a specification.

This invention relates to improvements in the manufacture of boots, shoes, sandals, slippers, or the like and also to improvements in soles for such articles. The improvements are particularly applicable to that type of boots or shoes which have soles composed of a wound or lapped band or bands secured together by transverse sewing.

Heretofore in the manufacture of such soles, after the winding or lapping of the band or bands, the sole is sewn longitudinally or radially at the heel and toe and transversely along its whole length. The operation of sewing the toe and heel is costly, as, when done by hand, it is very slow and laborious, and, when done by machine, skilled workmen are required as the operation is very intricate. Moreover a sole sewn at the heel and toe is flexible and has not suflicient rigidity at these parts. Again the heel and especially the toe portion of a known sole is of too rounded a form, the longitudinal and radial sewing at these parts preventing the sole being pressed into an elongated shape to procure a sole with a narrow rounded toe portion.

The object of the present invention is to obviate all the above mentioned disadvantages by providing means for securely closing the heel or toe portions without requiring same to be sewn longitudinally or radially, andthese means may at the same time be arranged to close the toe and heel portions of theupper.

According to the present invention the toe or heel portion is closed by means of a fastening member, such as for example a spearended nail or the like, which when introduced into the sole is adapted to take and securely hold a binding thread or the like. One, two or more fastening members may be employed. Preferably, the fastening membei' or members is or are arranged to engage with the end portions of the transverse stitching threads after same have been crossed or knotted at the toe or heel. If desired, however, a separate binding thread may be attached to one, two or more nails and secured in the sole. This latter method is especially suitable where the two ends of the threads of the transverse sewing are too short to allow of same being crossed or knotted.

The toe and heel portions of soles produced according to the present invention are of greater strength and rigidity than the toe and heel portions of the known soles. Again, according to the present invention, a sole with a narrow pointed toe can be easily obtained as the band or bands forming the toe portion are not pressed compactly against each other in the longitudinal direction as is the case when they are sewn longitudinally or radially, so that, from an equal length of band, a longer or more elongated sole can be obtained by the present invention than was heretofore possible. This has a monetary advantage as soles are sold according to their length or size. The main monetary advantage however lies in the low cost of the means for closing the heel and toe and in the fact that the operation is simple and can be executed by unskilled workmen either by hand or machine.

As the binding threads have been introduced into the sole, the ends of the latter present the same appearance as a sole which has been sewn at heel and toe. In the case where the upper is inserted between two lengths of the band or bands forming the sole and secured thereto by the transverse stitching, the fastening means may also be employed to close the heel and toe of the upper in addition to closing the heel or toe of the sole.

In the accompanying drawings, Figure 1 illustrates in section a sole which has been transversely sewn, and FiO. 2 shows the same sole partly in section af er the fastening members have been introduced into same. Fig. 3 is an enlarged end elevation of the heel portion of Fig. 2. Fig. l is a section of a heel portion showing the application of the fastening members when the ends of the transverse threads are too short to be crossed or knotted. Fig. 5 illustrates various forms of fastening members.

Referring to Figs. l to 5," the sole 1 is composed of a band Q (see Fig. t) wound in known manner, pressed, and transversely sewn along its whole length by means of two threads 3 and 4:. A series of soles are usually sewn one sole after the other in a transverse sewing machine, the soles being connected together by the threads 8 and 1i. These threads are cut at any convenient point, and the ends of the threads are crossed or knotted at the heel and toe as at 5, (see dotted lines in Fig. l). Fasteningl members 6 (shown also in dotted lines in Fig. l) are now introduced into the heel and toe portions and these members are pressed into the sole as shown in Fig. 2. rlhe fastening members 6, which may be of any convenient form or of any suitable material, are adapted to engage the end or ends of the transverse thread or threads and to pull these threads into the sole. Four convenient forms of fastening members are shown in Fig. 5, each member being provided with a cutting point 6a, and with a thread retaining portion 6b. The members are also formed with projecting portions 6 which engage with the sole Vand prevent the member working out or from being withdrawn without damage to the sole. The fastening members may be made of iron, steel, wood or any other suitable material.

VVliei-e the ends of the transverse threads are too short to allow of same being crossed or knotted, a separate thread or cord 7 may be secured in .any suitable manner to two or more fastening members. Fig. i shows a thread 7 secured to three fastening members.

If desired, a separate cord may be attached to one, two or more members and after insertion, the free end or ends of same may be tightly knotted to the ends of the transverse threads. rlhis modified method is not shown on the drawings but same will be readily understood.

lVhile one fastening member has been shown as applied to the toe portion and three fastening members as applied to the heel portion, it will also be readily understood that any convenient number of fastening members may be employed either at the heel or at the toe, and that these members may be arranged in any desired manner. For instance, the fastening members have been shown at the heel portion as inserted radially, but these may be inserted longitudinally or transversely if so desired.

ln practice, the uppers A are sometimes secured to the sole by being inserted. between the two outer layers of the band 2 and sewn transversely at the same time as said layers. In such cases, the fastening members also serve to close the heel and toe portions of the uppers in addition to closing the heel and toe portions of the soles. Where in other cases, the upper is secured to the sole by means of separate edge sewing, the fastening members may be pushed in sufficiently to leave a clear space for such edge sewing.
